mild stage starts with forgetting names, then the moderate stage comes with feeling withdrawn from family, and finally it’s the severe stage which is lose awareness of their surroundings. When an individual is diagnosed with Alzheimer's their brain neurons not only die, but their cortex and hippocampus actually shrinks in size causing the memory loss. To get deeper and go into cell growth and decay, abnormal clusters of protein fragments, build up between nerve cells known as plaques. Once the…

This essay is about the brain and the growth mindset. Did you know that the brain is the command center for the nervous system? Well yes, the nervous system is part of the brain. There are 100 billion neurons in our brain alone. The brain sends messages via the spinal cord to peripheral nerves throughout the body that serve to control the muscles and internal organs. The largest part of the brain is called the cerebrum. The cerebrum is divided into two cerebral hemispheres, which…

functioning normally Tau helps stabilize and support certain structures within the brain cell, but when the brain suffers a traumatic hit the proteins start to bend and clump furthermore, The build-up of these clumped proteins is what starts to kill the neurons and eventually the cell. The protein is then circulated throughout the brain, and this leads to the deaths of other cells. Currently, doctors can only diagnose CTE is after the player has died, that is because CTE needs to be diagnosed by…

Brain Implants. Introduction Brain implants, also known as neural implants, are technology implanting devices on surface of the brain that connects directly to the neural system. Some possible use for brain implant technology are treatment for brain disorder, restoring and enhancing of sensory system, and augmenting brain processing. In this paper, the ethical considerations of applying brain implant technology for both therapeutic and enhancement purpose will be examined. Overview of brain…

with advanced Alzheimer’s disease have a shriveled cortex, as well as an extremely shrunken hippocampus. The ventricles of the brain also increase largely in size, leaving less space for brain tissue. There are also a considerably less amount of neurons and synapses. Also, there a buildup of abnormal protein clusters between nerve cells, along side a build of twisted strands of protein called tangles building. These two protein buildups are thought to be a major cause of tissue death in the…

Our brains are made up of over 100 billion nerve cells that are called neurons. Large groups of these make up the brain regions and each region has its distinctive duties. Where does the abnormal behavior come from though? Researchers have learned that these disordes can be linked to the problem in the transmission of messages from neuron to neuron. Somewhere, somehow, a message is not getting across clearly. Not to mention, we also have hormones that are constantly…

advancing in age, family heritage, being male gender, or exposure to toxins. Ultimately, the resulting of Parkinson’s disease is also due to the deprivation of a chemical called dopamine. As Parkinson’s starts and evolves over time, the nerve (neurons)…

plaques and tangle bundle of fibers around the nerve cells. The plaques now a day are known as Amyloid plaques, which are made up of fragments of a protein called beta-amyloid peptide (Aβ) mixed with a collection of additional proteins, remnants of neurons, and bits and pieces of other nerve cells. To describe where Aβ originates, first we have to talk about the APP gene. APP gene is located on chromosome 21 and tells the cells how to make amyloid precursor protein. His protein is found in many…

This occurs when the brain’s neurons do not produce enough dopamine. According to, MNT (Medical News Today) website, there are a variety of potential causes for this disorder, including chronic stress, nutritional deficiencies, and medical conditions. Adrenal insufficiency, influenza…

from the Greek language. To break it down “A” means no “Myo” means muscle and “Trophic”means nourishment together it stands for no muscle nourishment. The word “Lateral” meaning the spinal cord in the body. ALS is an serious disease that affects the neurons, which controls the voluntary muscles when a muscle has no nourishment it becomes weak to control which then results into no communicating in the brain due to many repetitive head trauma. If the spinal cord gets affected due to ALS then the…
